Abstract:
A real-time video encoder is disclosed that changes video encoding processes to produce the best quality encoded video whilst maintaining a target encoding frame rate, according to one or more operating constraints. The systems and methods described here overcome the inflexibility of existing video encoders by providing best encoded picture quality during any system resource or picture characteristic variations. This is achieved by checking encoding progress regularly throughout an encode sequence, including checking encoding progress within a macroblock or intra -macroblock, and automatically adapting the encoder's use of encoding tools according to actual achieved encoding progress. No specific knowledge of, or measurement of, changes in system resources or picture characteristics is required.
Abstract:
Methods and apparatus for adaptive encoding of data such as for example video data. In one exemplary embodiment, a real-time video encoder is disclosed that changes video encoding processes to produce the best quality encoded video whilst maintaining a target encoding frame rate, according to one or more operating constraints.
Abstract:
Methods and systems for routing messages between a core network (302) and a radio network controller (102) are provided. A radio access network gateway (304) translates messages from an ATM-based protocol to a non-ATM-based protocol, such as the stream control transmission protocol and vice versa. The radio access network gateway (304) forwards the SCTP messages to the core network (302). In addition, the radio access network gateway (304) receives messages from the core network (302) formatted according to the core network protocol and translates these messages to an ATM-based protocol for communication to a radio network controller (102).

Abstract:
A presence registration and routing node (300) receives a message indicative of a telephony-related action performed by a user. In response to the message, the presence registration and routing node (300) sends a message (434) to a presence server (426) for updating presence information regarding the user in a presence server database.
